SUPPORTING-HOLDER FOR GLASS-MOLDS.

SPECIFICATION forming part of Letters Patent No. 481,142, dated August16, 1892. Application filed September 10, 1890. Renewed May 16, 1892.Serial No. 433,214. (No model.)

To all whom it may concern.-

Be it known that LULYssns S. HUGGINS, a citizen of the United States,residing at WVashington, in the county of Washington and State ofPennsylvania, have invented certain new and usefullmprovements inSupporting-Holders for Glass-Molds; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,which will enable others skilled in the art to which it appertains tomake and use the same.

My invention relates to various new and useful improvements in holdersfor glassmolds, whereby the mold may be securely locked in position whendesired, so as to be prevented from moving laterally or becomingaccidentally disarranged, and whereby the mold may be quickly and easilyremoved from the holder when it is so desired for cleaning or repairingthe same.

The principal object of my invention is to provide and produce a holderfor glass-molds, whereby the mold will be securely held in place and maybe removed when desired.

Another object of my invention is to provide a holder for molds by whichmolds of different sizes and shapes may be held so as to be on the samelevel.

A further object of my invention is to provide certain auxiliaryattachments to my device, whereby the mold may be quickly removed fromthe holder when desired.

The principal novelties in my invention consist in providing an ordinarysectional mold with a separate T-headed tenon on one of its parts; inproviding the holder with a corresponding mortised I-groove, with whichsaid tenon engages; in providing certain looking mechanism for securingthe tenon in place in said mortise; in pivoting a double lever withinthe holder, with which the movable section of the mold engages, and inmounting a weight on the other end of this lever for closing the mold,as Well as in other but less important construction, all as will be morefully hereinafter described and claimed.

For a better comprehension of my invention attention is invited to theaccompanying drawings, forming a part of this specification, and inwhich Figure 1 is a vertical sectional view of my invention on the linesac to; Fig. 2, a top view of a number ofmold-holders and molds, showingthe manner of attachingthe same together; Fig. 3,a top view of a holderproper, and Fig. 4 an enlarged vertical sectional view showing themanner of locking the molds in position.

In all of the above views corresponding parts are designated by the sameletters of reference.

The holder consists of a side A A, the bottom B, and the centralpartition 0. The front of each side A is cut away on an incline, asshown, in order to save the material and to allow for the easy access toall parts of the mold. The partition 0 extends across from side to side.This partition 0 is divided into two parts by means of a vertical slotat. Surrounding this slot at the rear of the partition is a casing D,which is preferably cast integral with the partition.

E represents an ordinary mold, made of iron or steel, in two partspivoted at their lower ends so as to open outwardly, in order that thebloom may be inserted in the mold and that the completed article may bewithdrawn from the mold, as will be understood by those skilled in theart of glass-making. Secured to one section of this mold is a metallictenon F, which is preferably held in position by means of set-screws Z).This tenon is provided with a large head 0, adapted to fit within theeasing 1), and with a smaller neck portion (1, which engages with theslot to in the partition 0. By this means the tenon F may be made toengage with the casing D, so as to be held securely therein.

At the upper portion of the rear Wall of the casing D an opening 8 isformed,which is enlarged at its lower end or near the same, as will beseen, so as to communicate with the space Within the casing. Engagingwith this opening c is a pin or stud f, having a rectangular head g.This pin or stud is also provided with a cam portion h, which workswithin the enlargement therein. After the head 0 of the tenon F has beeninserted within the casing D the pin or stud f may be turned partlyaround by means of a key engaging with the headed portion thereof, sothat the cam portion it will engage tightly against the tenon, so as tolock the same securely in place within the casing. By this means it willbe seen that the mold may be locked at any height within the casing D,and it will therefore be evident that molds of different sizes may belocked in adjoining holders, so as to be all on the same plane.

At the lower portion, near the front of the inside of each piece A, iscast or secured a small block hollowed out on its upper face, so as toform a pivoting-piece. Pivotally mounted within each of these blocks isa lever G, having a small depending stem, which bears within the groovedblock i 011 each side. The forward end of each lever G is connected tothe corresponding end of the other lever by means of a connecting-rod7a. The bottom portion of the movable portion of the mold engages withthis connecting-rod and will operate the same as the mold is opened orclosed. Hearing on the other end of each 1ever is a weight II, which isadapted to move vertically upward and downward within the holderdirectly in the rear of the partition C. It will now be seen that whenthe mold is open the forward portion of the levers will be moveddownwardly and the weight will be elevated. I prefer to make the weightII of such dimensions as to exactly counterbalance the movable portionof the mold E. To the upper side of this weight is attached a verticalstandard 71, to the upper extremity of which is secured a pedal orhandle 0 in. any suitable manner.

In order that the mold may be removed from the holder when necessary, Imake use of the device illustrated in Fig. 1 and which will now bedescribed. Each section of the mold is provided with a screw-threadedchamber Z, cut in its upper face. When it is desired to remove the moldfrom the holder, I screw within each openingZ a small handle m, by whichthe mold may be raised from its position within the holder.

It is intended that a number of these holders are to be placed side byside Within the pit, so as to be under the supervision of oneglass-blower, who stands at a point on a level with the top of theholder and with his foot in convenient distance of the pedal 0. Inoperation the glass-blower blows the article in the usual manner,keeping the mold closed by applying his foot to the pedal 0. After themold is filled and the article blown the mold is opened by means of ahandle or similar device 1), rigidly secured to the mold E, by anassistant who stands in the pit below the glass-blower. This assistantalso removes the finished article by means of any suitable instrument.These holders may be securely fastencd together by means of boltspassing through the adjacent sides of each.

Having now described my invention, what I claim as new therein is asfollows:

1. The combination of a supporting'frame having a number of mortisestherein, one or more molds each provided with a tenon F, engaging witheach mortise, and a cam-bolt q for locking said tenon in place in saidmortise, substantially as set forth.

2. The combination of a supporting-frame having a number of mortisestherein, one or more molds each provided with a tenon F, engaging witheach mortise, a cam-bolt g for locking said tenon in place in saidmortise, a counterbalaneing-weight II for each mold, and a lever G, uponwhich bear the said counterbalancingweight and the moving part of eachmold.

ULYSSES S. l'lUGGINS.
